본 고안은 듀우서어보식 드럼브레이크의 스프링고정장치에 관한 것으로, 특히, 작업공정을 간소화하고 스프링의 결속력을 증대시킬수 있게하는 듀우서어보식 드럼브레이크의 스프링고정장치에 관한 것이다.The present invention relates to a spring fixing device of the duo servobore drum brake, and more particularly, to a spring fixing device of the duo servobore drum brake to simplify the work process and increase the binding force of the spring.
유압실린더의 일종인 듀우서어보식 드럼브레이크는 드럼지롬의 제약을 받는 승용차등에서 많이 사용되어지고 있는 것으로, 그러한 듀우서어보식 드럼브레이크는 전, 후진시 모두 자기작동이 일어나 강력한 제동력이 발생하기 때문에 드럼직경에 제약을 받는 승용차등에 널리사용되고 있는데, 이러한 듀우서어보식 드럼브레이크는 동일한 직경의 휘일실린더와 조정기로 연결한 두개의 슈우와 하나의 앵커로 구성되어 슈우가 드럼에 압착되면 드럼의 회전방향에 따라 슈우의 고정측이 바뀌어 자기의 작동이 모든 슈우에 일어나 바퀴를 제동시키게 되는 것이다.The duo-serbo-type drum brake, a kind of hydraulic cylinder, is widely used in passenger cars, which are constrained by the drum gyro. It is widely used in passenger cars, etc., which are constrained by heavy duty. These duo-cerbo drum drums are composed of two cylinders of the same diameter and a shoe connected to a regulator, and one anchor. The right side of the right side is changed so that the movement of all the shoes occurs to brake the wheels.
이와같은 듀우서어보식 드럼브레이크에 있어 휘일실린더에 유압이 작용하게되면 슈우가 배킹플레이트에 지지되어 드럼에 압착 또는 복귀될 수 있도록 슈우와 배킹플레이트에 스프링이 고정설치된 것으로, 종래의 스프링 고정장치는 제3도에서와 같이 배킹플레이트(1)의 상면에 절곡형 고정구(18)를 용접에 의해 부착시켜서 이 고정구(18)와 슈우(4) 내측으로 구비된 걸림부(41)에 스프링(7)을 걸어 고정설치하여 왔다.When the hydraulic pressure acts on the wheel cylinder in the duo servobore drum brake, the spring is fixed to the shoe and the backing plate so that the shoe is supported by the backing plate and pressed or returned to the drum. As shown in FIG. 3, the bent fastener 18 is attached to the upper surface of the backing plate 1 by welding to attach the spring 7 to the engaging portion 41 provided inside the fastener 18 and the shoe 4. It has been fixed by hanging.
그런데 상기에서와같은 종래의 스프링 고정장치는 고정구를 별도로 제작하여 부품조립이전에 용접으로 부설시켜야 하는 작업의 번거로움이 있었을뿐 아니라, 사용시 용접부위가 이탈되어 제동기능을 손상시키게 하는 결함이 있었다.By the way, the conventional spring fixing device as described above was not only hassle of the work to be laid by welding before assembling the parts separately, there is a defect that damages the braking function due to the welding part is separated during use.
이에 본 고안은 상술한 바와같은 종래의 제반결함을 감안하여 이루어진 것으로 그 목적은 작업공정을 간소화함과 아울러 스프링의 결속력을 증대시킬 수 있게하는 듀우서어보식 드럼브레이크의 스프링 고정장치를 제공함에 있다.Accordingly, the present invention has been made in view of the above-mentioned conventional defects, and an object thereof is to provide a spring fixing device for a duo-cerbo drum drum brake that can simplify the work process and increase the binding force of the spring.
이러한 본 고안의 목적은 배킹플레이트와 일체로 구비되는 스프링고정장치를 제공함에 의해 달성되는데, 이 스프링고정장치는 배킹플레이트 소정위치의 양측에 엔보싱가공으로 돌설시킨 고정구를 갖추어서 이루어지는 것이다.The object of the present invention is achieved by providing a spring fixing device which is provided integrally with the backing plate, the spring fixing device is provided with a fixture which is protruded by the enbossing process on both sides of the predetermined position of the backing plate.
이하, 첨부된 도면을 참조하여 본고안 일실시예의 구성을 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of an embodiment of the present invention.
제1도는 본 고안이 적용된 듀우서어보식 드럼브레이크의 평면도로서, 이 드럼브레이크는 배킹플레이트(1)의 상부에 동일한 직경의 휘일실린더(2)와 조정기(3)에 두개의 슈우(4)가 연결되고 이 슈우(4)는 상부중앙에서 하나의 앵커핀(5)으로 연결되어 있어 브레이크패달을 밟아 매스터실린더로 부터 휘일실린더(2)에 유압이 전달되면 드럼(6)와 회전방향에 따라 슈우고정측이 바뀌어 자기의 작동이 슈우(4)에 일어나 바퀴를 제동시키게 되는 것이다.FIG. 1 is a plan view of a duocerbobo drum brake to which the present invention is applied. The drum brake is connected to the wheel cylinder 2 having the same diameter on the top of the backing plate 1 and the two shoe 4 connected to the adjuster 3. This shoe (4) is connected to one anchor pin (5) in the upper center, and when the hydraulic pedal is transmitted from the master cylinder to the wheel cylinder (2) by stepping on the brake pedal, The front side is changed so that the magnetic action occurs on the shoe 4 to brake the wheels.
이러한 통상의 듀우서어보식 드럼브레이크에 있어 본고안은 슈우(4)가 배킹 플레이트(1)에 지지되어 드럼(6) 압착된후 원상태로 복귀될 수 있도록 하는 스프링(7)의 고정장치를 배킹플레이트(1)에 일체로 구비하게 되는데, 이 고정장치가 제2도에서 결합상태 단면도와 요부발췌사시도로 도시되어 있다.In this conventional duocerbobo drum brake, the present invention provides a backing plate for fixing the spring 7 so that the shoe 4 is supported by the backing plate 1 so that the drum 6 can be compressed and then returned to its original state. It is provided integrally with (1), and this fixing device is shown in FIG.
본 고안 고정장치는 배킹플레이트(1)의 제작시 중앙양측에 대향으로 엔보싱 가공에 의해 걸림공(81)이 형성되도록 상향으로 돌설시킨 고정구(8)를 갖추어서 이 고정구(8)의 걸립공(81)과 슈우(4)의 걸림구(41)에 스프링(7)의 양단을 끼웡 고정설치하게 되는 것이다.The fixing device of the present invention is equipped with a fastener 8 which protrudes upward so that the engaging hole 81 is formed by enbossing to face the center at both sides when the backing plate 1 is manufactured. Both ends of the spring 7 are fixed to the engaging holes 41 of the 81 and the shoe 4.
따라서 이상에서와 같이 구성된 본 고안은 고정구가 배킹플레이트의 제작시 일체로 구성되어지므로서, 작업공정이 간소화 될뿐만 아니라 스프링의 견고하고 안정된 결속으로 제동기능의 신뢰성을 증대시킬수 있게 함을 특징으로 하는 것이다.Therefore, the present invention configured as described above is characterized in that the fastener is integrally configured at the time of manufacturing the backing plate, which not only simplifies the working process but also increases the reliability of the braking function by the firm and stable binding of the spring. will be.
